Hauv kev sib zog ua kom cov khoom siv biomaterials tuaj yeem siv tau ntau dua, cov kws tshawb fawb ntawm University of California, Berkeley tau sib txuas 2D bioprinting, ib caj npab neeg hlau rau 3D sib dhos, thiab flash khov rau hauv ib txoj kev uas tuaj yeem muaj ib hnub ua rau luam ntawv ntawm cov ntaub so ntswg nyob thiab txawm tias. tag nrho lub cev. Los ntawm kev luam cov khoom nruab nrog rau hauv cov ntawv nyias nyias, tom qab ntawd khov lawv thiab muab tso rau lawv raws li cov txheej txheem, cov thev naus laus zis tshiab txhim kho qhov muaj sia nyob ntawm biocells ob qho tib si thaum luam ntawv thiab thaum khaws cia tom ntej.
Biomaterials muaj peev xwm loj heev rau cov tshuaj yav tom ntej. 3D luam ntawv siv tus neeg mob tus kheej cov qia hlwb yuav pab tsim cov kabmob rau kev hloov pauv uas tau ua tiav thiab yuav tsis ua rau tsis lees paub.
Qhov teeb meem yog tias cov txheej txheem bioprinting tam sim no qeeb thiab tsis ua kom zoo heev vim tias cov hlwb muaj lub sijhawm nyuaj rau txoj kev luam ntawv yam tsis muaj kev tswj xyuas qhov kub thiab txias heev. Tsis tas li ntawd, qhov nyuaj ntxiv yog raug txwv los ntawm kev khaws cia ntxiv thiab kev thauj mus los ntawm cov ntaub ntawv luam tawm.
Txhawm rau kov yeej cov teeb meem no, pab pawg Berkeley tau txiav txim siab ua kom sib npaug ntawm cov txheej txheem luam ntawv thiab faib ua ntu ntu. Ntawd yog, es tsis txhob luam tawm tag nrho cov khoom nruab nrog ib zaug, cov ntaub so ntswg tau luam tawm ib txhij hauv XNUMXD txheej, uas tom qab ntawd muab tso rau ntawm caj npab neeg hlau los tsim cov qauv XNUMXD kawg.
Txoj hauv kev no twb tau ua kom cov txheej txheem nrawm, tab sis kom txo qis kev tuag ntawm tes, cov khaubncaws sab nraud povtseg tam sim ntawd rau hauv lub da dej cryogenic kom khov lawv. Raws li pab neeg no, qhov no ua rau muaj txiaj ntsig zoo rau kev muaj sia nyob ntawm cov ntaub ntawv luam tawm thaum khaws cia thiab kev thauj mus los.
"Tam sim no, bioprinting feem ntau yog siv los tsim cov ntaub so ntswg me me," hais tias Boris Rubinsky, tus kws tshaj lij ntawm kev siv tshuab engineering. "Qhov teeb meem nrog 3D bioprinting yog tias nws yog txheej txheem qeeb heev, yog li koj yuav tsis muaj peev xwm luam tawm dab tsi loj vim tias cov ntaub ntawv lom neeg yuav tuag thaum koj ua tiav. Ib qho ntawm peb qhov kev tsim kho tshiab yog tias peb khov cov ntaub so ntswg thaum peb luam tawm, yog li cov khoom siv roj ntsha tau khaws cia. "
Pab neeg no lees paub tias qhov kev ua ntau yam no rau 3D luam ntawv tsis yog tshiab, tab sis nws daim ntawv thov rau biomaterials yog qhov tshiab. Qhov no tso cai rau cov khaubncaws sab nraud povtseg hauv ib qho chaw thiab tom qab ntawd thauj mus rau lwm qhov rau kev sib dhos.
Ntxiv nrog rau kev tsim cov ntaub so ntswg thiab lub cev, cov txheej txheem no muaj lwm yam kev siv, xws li hauv kev tsim cov khoom noj khov rau ntawm qhov chaw lag luam.
Txoj kev tshawb no tau luam tawm nyob rau hauv .
